Philippe, Are you using Jessie or Wheezy ? I have seen some interesting performance differences between the versions of DBIx shipped with these Debian versions. Jessie is much faster.

I got a question to all the dbix experts out there (I'm not one of them, unfortunatly). I have performance issues in the checkout that remains even after boosting my server's performance with a SSD drive. In C4/Circulation.pm/AddIssue, a lot of transactions take >1s for the call to schema $issue = Koha::Database->new()->schema()->resultset('Issue')->create( This is 3.20. I specifically isolated that call with timers, I do a bunch of checkouts for the same user, and repetitively, that call take over 1s. The machine is a beast (ram, cpu...), so what should I be doing?
